Talent is not art. Art is served by talent. Art needs discipline and technique and execution, these aspects are well addressed by the voice and satisfy 90% . Art however is less tangible, more personal. Many artists I love would most likely never even make it on the voice and succeeded despite being critically panned in their time. It would be a pretty narrow and boring musical world if it all was funneled through a game show mindset.
I've heard Grimmie, she was a great singer but art? performer for sure, but art? I'm not so sure.
